From Flora of Indiana (1940) by Charles C. Deam

This mint is local and rare in the state but where it is found there are usually several plants in a colony or it is found growing for some distance in its restricted habitat. It grows in deep leaf mold in cool, moist places, usually toward the bases of deep, wooded ravines. Rarely found in level woods where it grows in dense shade.
